With nar-bridge supporting zstd content-encoding, we don't need the
nginx zstd module and can re-enable http2.
We also need to propagate the Accept-Encoding sent by the client to
nar-bridge, so it actually knows it can send zstd.
This reduces the time measured in the microbenchmark from ~13s to this:
```
hyperfine 'rm -rf /tmp/cache; nix copy --from https://nixos.tvix.store/ --to "file:///tmp/cache?compression=none" /nix/store/jlkypcf54nrh4n6r0l62ryx93z752hb2-firefox-132.0'

We don't need a separate instance of opentelemetry-collector, alloy can
also do this job for us.

These are quite bursty, and I've seen messages about getting rate
limited.

This enables routing of metrics to an instance of VictoriaMetrics, and
configures opentelemetry-collector to route metrics there.

This is a fetch-through mirror of cache.nixos.org, hosted by NumTide.
The current machine is a SX65 Hetzner dedicated server with 4x22TB SATA disks,
and 2x1TB NVMe disks.
The goals of this machine:
- Exercise tvix-store and nar-bridge code
- Collect usage metrics (see https://nixos.tvix.store/grafana)
- Identify bottlenecks
- Replace cache.nixos.org?
Be however aware that there's zero availability guarantees. Since Tvix doesn't
support garbage collection yet, we either will delete data or order a bigger
box.
